Hastelloy alloys have long been the gold standard of corrosion resistant bolts; only out performed by metals like Zirconium and Tantalum. This family of high performance nickel alloys can handle strong acids like hydrochloric, sulfuric, acetic, formic and phosphoric acids, yet each grade actually exhibits its own strengths in dealing with specific acids and niche environments. … Continue reading →
